Feature request: allow undeclared test outputs to be collected unzipped

[paullewis]

Description of the feature request:

I currently have some test runners that output XML reports, which can be collected in TEST_UNDECLARED_OUTPUTS_DIR. However these files are always zipped as per https://github.com/bazelbuild/bazel/blob/master/tools/test/test-setup.sh#L409-L419

I was wondering if it would be possible to add a flag/option that bypasses the zipping process and instead puts the files as-is in the testlogs dir where the outputs.zip file would have been?

What underlying problem are you trying to solve with this feature?

I don't always want the unspecified test outputs to be zipped to outputs.zip as I end up having to unzip them again to do further processing on their contents.

Which operating system are you running Bazel on?

Mac

What is the output of bazel info release?

release 5.2.0

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

What's the output of git remote get-url origin; git rev-parse master; git rev-parse HEAD ?

9c00adcf27f75cb9d606c3d90fc0b0307830b952

Have you found anything relevant by searching the web?

A few items, but all the stuff I found assumes that there will always be an outputs.zip (which tallies with how I read the Bazel source).

Any other information, logs, or outputs that you want to share?
